haproxy 超時機制

 

<pre name="code" class="python">option  redispatch  option redispatch   是否允許重新分配在session 失敗后  
      
option abortonclose 丟棄由於客戶端等待時間過長而關閉連接但仍在haproxy等待隊列中的請求  
  
  
    option abortonclose  
  
    #當服務器負載很高的時候，自動結束掉當前隊列處理比較久的鏈接    
  
defaults  
        log     global  
        mode    http  
        option  httplog  
        option  dontlognull  
        retries 3  
        option  redispatch  
        option  abortonclose  
        maxconn 65535  
        timeout connect 5000  
        timeout client  50000  
        timeout server 50000  
  
        timeout check   5s  
        stats   refresh 30s  
  
  
timeout http request ：在客戶端建立連接但不請求數據時，關閉客戶端連接  
timeout queue ：等待最大時長  
timeout connect： 定義haproxy將客戶端請求轉發至后端服務器所等待的超時時長  
timeout client：客戶端非活動狀態的超時時長  
timeout server：客戶端與服務器端建立連接后，等待服務器端的超時時長，  
timeout http-keep-alive ：定義保持連接的超時時長  
timeout check：健康狀態監測時的超時時間，過短會誤判，過長資源消耗  
  
  
  
client_timeout 是 app 連接 haproxy的時間  
server_timeout 是haproxy 連接后端的時間.  
  
目前發現 超時后,前台一個點擊 haproxy 會收到兩個相同的請求,原因待查明。  
  
  
  
  
  
  
設置 5秒超時時:  
     timeout connect 5000  
        timeout client  50000  
        timeout server 50000  
  
        timeout check   5s  
        stats   refresh 30s
